Are you saying that when you disconnect the quick connect, it actuates the QEV? If so, install a ball valve after the quick connect as a safety feature, so before disconnecting the quick connect you shut off the ball valve, and only the air between the ball valve and connect gets vented.

Mmm, I was getting pissed off at the poor performance of the check valve in the bike valve I used for my cannon during mid-construction testing so I added a proper check valve which cured all problems.

A quick connect plug attached to the QEV, when disconnected from the quick connect socket, it will have far greater flow than that of a blowgun. I find blowguns are pretty poor pilot valve unless they're on a sprinkler valve or on a 1/4" QEV attached to a 1/2" QEV

edit:

i just tried with a ball valve got same result still not fully open

The 1/4" QEV or the 1/2" QEV didn't fully open? You must have a massive pilot volume, can you post a picture?

i will try tommorw had a long work day but it has a 1/8 stanless steal tube. i think ten inches and it goes to a blow gun and check valve my 1/4 qev is a diagram the 1/2 piston
looks like heal but tryin to make it a semi

What type of blowgun are you using because i had one that had less flow than a schrader! if you are using those red trigger ones i would try taking away the 1/4 QEV and putting the blowgun there instead it worked fine in mine and it wont change the performance that much.
